How To Choose a Window Company in St. George

With St. George's large population, you're sure to find a trustworthy window company that aligns with your values and preferences. As you contact companies, keep the following factors in mind:

Window Cost by Type

When it comes to window replacement, value is paramount. Each window you purchase should offer optimal durability at a reasonable price point. Although high-quality windows may cost more upfront, they often provide better long-term value due to their increased lifespan. The size, material, and style of your new windows have the greatest impact on your final cost. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. A professional can guide you through picking the products that fit your preferences.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Glass Block$40-$513

Window Material Cost

You'll also need to select a window material. Homeowners frequently make their selection by considering the local climate, energy efficiency objectives and aesthetic preferences. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows up-front, but you'll need to invest in regular maintenance to prevent the frame from warping and wear. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window TypesAverage Cost

Other Window Replacement Costs

Your total cost for window replacement will also include warranty fees (if applicable), permit application fees, and labor. Be sure to discuss each of these elements with a sales representative before committing to a window company.

Experience and Training

Choose a business that focuses on window repair and installation, and look for this information on its website:

  • How long it's been in business
  • Photo galleries of projects its crews completed
  • Private credentials attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

Utah requires every residential contracting business to be licensed with the state government. The application process is strict and requires four thousand hours of experience, 25–30 hours of training, and a trade exam. Window installers might need an S230 Specialty Contractors' License that authorizes them to work with glass.

Types of Windows Offered

There are several replacement window types you can choose from, and it's crucial to find a company that focuses on installing the ones you want. Check a company's website and reviews for any of these types:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Finally, pay close attention to the framing materials that an installer uses. Each frame material has a different life span, price point and energy efficiency level. A company will usually specify whether the windows they place use fiberglass, wood, vinyl, metal, or composite.

Customer Feedback

One of the simplest ways to evaluate a company is to see what other customers have written about their experiences. You can find customer reviews on websites like Google, Trustpilot, the BBB, and Yelp. Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.

Frequently Asked Questions About Window Replacement in St. George

How much energy and money will I save by upgrading my windows?

St. George homeowners could potentially save $340 per year by switching to efficient windows. They'll also lower their property's carbon dioxide emissions by 240 pounds per year.

According to the national Department of Energy, up to a third of a house's HVAC usage is to compensate for the heat or cold entering through windows. Efficient windows help keep heat out in the summertime and retain heat in the wintertime, improving your comfort and furthering your dollar.

I've heard there are tax credits for energy-efficient windows. How much could I save?

Ultimately, the tax incentives you can claim are determined by the scope of your window replacement and the community you live in. You can claim up to 30% of the value of new efficient windows as a federal tax credit, up to $3,200 per year, until 2032. We also encourage you to get in touch with your local building department for more information on financial benefits specific to your area.

What's the typical timeline for a professional window replacement?

The length of a window replacement project depends on several factors. It usually takes up to a month for the contractor to receive your windows from the manufacturer. The installation process itself often takes 40–60 minutes per window. However, larger windows or more complex installations may require additional time.
